Find the circumference and area of a circle with a diameter of 7cm. Round your answers to the hundredth.

a. C = 21.98cm and A = 38.47cm squared
b. C = 21.98cm and A = 153.86cm squared
c. C = 43.96cm and A = 38.47cm squared
d. C = 43.96cm and A = 153.86cm squared

Answers

Answer 1

Answer:

a.

Step-by-step explanation:

diameter 7cm

radius 3.5cm

area =πr²

=22/7* 3.5²

=38.47cm²

circumference=πd

=22/7* 7

=22cm

Answer 2

Answer:

a. C = 21.98cm and A = 38.47cm squared

Step-by-step explanation:

Diameter is twice the radius. Therefore radius, r, is 3.5cm.

Circumference = 2πr =2π(3.5)=7π=21.98cm

Area=πr²=π(3.5²)=12.25π=38.47cm²

What is the answer no link no links I will report the answer is not 70%

Answers

Answer:

75%

Step-by-step explanation:

Answer:

75%

Step-by-step explanation:

In a box-and-whisker plot, the whiskers show the minimum and maximum while the edges of the box show the first and third quartiles. The line in the box shows the median.

Quartile means a quarter of the data.

We're trying to find out what percentage of the students scored between 70 and 100.

70 is right on the 1st quartile mark, while 100 is on the maximum mark.

This means that a quarter of students got lower than 70, and nobody scored over 100 (because it's a test and it's calculated in percentage).

If a quarter of students got lower than 70, that means three-quarters of students got 70 or higher. And since the maximum is 100, and that is also what we're trying to find, the answer is 3/4 of all students.

3/4 = 75%

Hence, the answer is 75%.

94 hours to 8 days​

Answers

Answer:

11.75:1

Step-by-step explanation:

alrighty right, more unit rates, so we have to get that 8 down to 1. How are we gonna do that? By dividing it by 8. And if we divide one side by 8, we also have to divide the other side:

8 ÷ 8 = 1

94 ÷ 8 = 11.75

So 94 hours to 8 days in lowest terms is 11.75 hours to 1 day

Which of Seth's factor pairs contains only composite numbers?
F 6 x 22
G 11 x 12
H 3 x 44
J 2 x 66

Answers

Answer:

F. 6 x 22

Step-by-step explanation:

6 has more than two factors ( 1, 6, 2, 3), which makes it a composite number.22 has more than two factors (1, 22, 2, 11), which makes it a composite number.Therefore, F is the correct answer.

The Seth's factor pairs that contains only composite numbers are

6 × 22.

Composite numbers are numbers with more than 2 factors.

They are natural numbers or positive integers with more than 2 factors. Examples are 15, 10, 20 etc...

The Seth's factor pairs that contains only composite numbers are

6 × 22.

The factors of 6 are 1, 2, 3 and 6

The factors of 22 are 1, 2, 11 and 22.

They both have more than 2 factors.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

We have two planes, Y and Z intersecting each other.

The intersection of two lines is a point.

As we know, if the two planes intersect each other, the intersection will be a line.

If planes are parallel then there will no intersection.

Thus, the statement first “The intersection of two planes is a line." option (a) is correct.

Answer:

Perimeter of figure = 36.3

Step-by-step explanation:

We'll begin by calculating the perimeter of the rectangle. This can be obtained as follow:

Length (L) = 9

Width (W = 4

Perimeter of rectangle (Pᵣ) =?

Pᵣ = 2(L + W)

Pᵣ = 2(9 + 4)

Pᵣ = 2(13)

Pᵣ = 26

Next, we shall determine the perimeter of semi circle. This can be obtained as follow:

Diameter (d) = 4

Pi (π) = 3.14

Perimeter of semi circle (Pₛ) =?

Pₛ = ½(πd) + d

Pₛ = ½(3.14 × 4) + 4

Pₛ = ½(12.56) + 4

Pₛ = 6.28 + 4

Pₛ = 10.28

Finally, we shall determine the perimeter of the figure. This can be obtained as follow:

Perimeter of rectangle (Pᵣ) = 26

Perimeter of semi circle (Pₛ) = 10.28

Perimeter of figure =?

Perimeter of figure = Pᵣ + Pₛ

Perimeter of figure = 26 + 10.28

Perimeter of figure = 36.28 ≈ 36.3

The compounded amount after 10 years would be $1,458,293.87.

What is the formula to calculate the compound interest?

The formula to calculate the compound interest is -

[tex]$A =P(1 + \frac{r}{n}) ^{nt}[/tex]

Given is that Phillip decides to invest $800,000 in a period annuity that earns 5.2% APR compounded monthly for a period of 20 years.

We can calculate the compounded amount as -

A = 800000(1 + 0.052/12)^(12 x 20)

A = 1,458,293.87

Therefore, the compounded amount after 10 years would be $1,458,293.87.

Therefore, obtuaking the critical value using a T-test distribution at 95% confidence level.

(1 - 95%) / 2 = (1 - 0.95) / 2 = 0.05 / 2 = 0.025
